Cummins 6.7L Exhaust Brake vs Continental Divide (Super C RV)

We put our Nexus Wraith Super C RV and its 6.7l Cummins and Allison transmission to the test against the Continental Divide around Butte, Montana. Last in 2020 we added an exhaust brake and we wanted to test it in the Rockies vs the Appalachian Mountains.
There have been a lot of people who have been getting their Cummins engines power uprated, so we wanted to see just how "bad" or slow this Super C would be going up in the Rocky Mountains. Is it really that bad? Does it really need more power to make those grades bearable?
In the Appalachian mountains around the Smoky Mountains, we were going 40-45 mph up those grades. (check out this video where we show that)
• Taking The Super C Fro...
In the Rockies, we were able to hold 50mph almost the entire pull, where it only dipped down to 46 for a few seconds then back up to 50-55!
We think the Wraith did a great job, both going up, and down the Divide!
What do you think? Would you get the power upgrade and risk the transmission, or would you rather spend money on an exhaust brake to help with the dissent down the mountains/hills?
Leave a comment below!
Give this video a like if you think the Super C did a great job either way!

Exhaust brakes are such a game changer, especially living out west and having to go over mountains in any direction you travel. My question is, with turning on the exhaust brake oil pressure builds, is there a threshold to watch for when having the exhaust brake on for too long on a long grade?

Question: Would knowing what you know now preclude you from buying the Wraith again and/or would you look to buy something with more power and torque?

[@WanderingWagners]

The wraith has done everything we've asked of it. We wouldn't hesitate to buy one again. For the price we couldn't say no. At the time it was $140k brand new vs $250k for other brands. If we did it again though we would order it with liquid spring or get it installed right away. Some people chase power and go for the models with 360hp but we don't have any complaints towing our Jeep.

I love exhaust brakes. We eventually started getting fire apparatus with them before I retired. We were just getting DEF units when I left. What a pain in the arse! 🤣 my class C E-350 doesn’t have an exhaust brake, but I always drive with tow/haul engaged even the few times I’m not towing my 4 door wrangler. I feel as far as the stock chassis is concerned, it’s hauling the big box full of things on its frame. I’m mostly a right laner, no more than 65 MPH, and nearly always in cruise control on the highway. Even through the hills I let it control speed. I feel it’s saving on brakes as it’s controlling speed without my input.

Exhaust brake, for sure. . .! Didn't sound like the truck was struggling that hard going up, but that down can really kill a rig!! Just curious, do you have the ability to monitor that Alison transmission temp, and if so, how much harder was it working, and how much higher did your temp climb? I know my Silverado temp starts going up during a pull uphill with my camper -- just wondering what you were experiencing!!

[@WanderingWagners]

The transmission runs about 150 on flat land and it was 165 in the mountains.

[@Big.Ron1]

I would be going for the exhaust brake now and at tranny rebuild time I would replace it with a 3000 or if that is not doable then upgrade the internals to hold 880 torque and then bump up the power. Your rig is light. I assume 12k front and 20k rear axles? It did very well. Be safe.

[@WanderingWagners]

Exhaust brake was by far the better choice. Now if the transmission could handle it, we'd definitely consider upping the power but we dealt with enough of rebuilding transmissions when we were drag racers haha

[@edwardhorvat2770]

Back when I was driving a truck I had an engine brake but they’re just the same as an exhaust brake I would go with the exhaust break it’s feels much more safer. You don’t smoke your brakes and you’re right in an automatic transmission. Those things you can maybe put 50 more extra horsepower, but I would not do that, my Duramax in my Chevy pick up truck is good for 50 more horsepower but I would never put a chip in my computer. I am looking into a pack brake exhaust brake since my diesels an old one it’s an 03 you got a watch so you don’t hurt the valve springs and from what I’m finding out pack break has a pretty nice set up for the older diesels gonna look into that, because I load very very heavy and my travel trailer is heavy to begin with. You can always see me coming down the road with a cord of firewood in the bed of my truck but yes, I would definitely recommend exhaust brakes over boosting the horsepower yeah some of the mountains here in Pennsylvania I can only do 60 mile an hour but I don’t wanna go any faster than that. I’m just wasting fuel I’m happy with my 14 modded a gallon that I get out in Ohio. There’s no way I get 14 moderate a gallon in Pennsylvania. That’s one of the reasons why we like Ohio being so flat Again another nice video. Thanks for all your hard work guys. Hopefully sometime we will meet up.

Another great vid guys! Definitely exhaust brake. I have yet to install the exhaust brake on our 2016 Ghost because our local International maintenance facility said they’d have to price it out as a factory build and they never got back to me before our cross country trip started so we are negotiating the mountains with no exhaust brake. This is our 3rd cross country trip and I’ve become used to slowing down to 45ish and put in 4th gear on downward grades and only occasionally use the brakes for 5 seconds or so at a time to maintain that speed. On steep up grades I am able to maintain 45ish on all but the steepest grades, then it’s normally 35-40 mph. Exhaust brake is definitely an upgrade I want to do once we get back. Just for cost comparisons what it it run you to have installed?

Ours was under $500. All they had to do on our chassis was install the switch on the dash and enable it in the programming. Best $500 we've spent.

I guess my decision would be based on where most of your travels are done. Your "out west" needs to be qualified. If you are in Colorado and climbing passes at 1100' to 1200' things are different. Especially if you have something naturally aspirated with the Oxygen thinner. Our former 2016 Tiffin gas Motorhome barely could do 35 mph over wolf creek and Laveta passes. Just crossing a divide is misleading. All that means is which direction the water travels either Atlantic or Pacific. In places where the topography isn't as high as in the Rockies such as in Montana you may be fine. That said most roads usually offer passing lanes so it's a personal decision. But I am in total agreement with getting a exhaust or Jake first. You won't find runout lanes going uphill but many trucks including pickups hauling RV's have burnt there brakes up going down hill. I use tow haul mode going down these passes even though I am not towing to reduce braking and rely on the engine and transmission more. Great content.

An exhaust brake uses the turbo vanes to create exhaust back pressure. An engine brake changes the timing of the exhaust valves which creates back pressure. Both will slow you down but an engine brake is far more effective. Do you know what engine you have?

@@WanderingWagners Curious what the temps run pulling the jeep when the outside temps get up in the 90's and low 100's. We are fixing to buy a super C and going to pull a Jeep Gladiator.

So far it's been running 150 degrees on flat land and about 165 in the mountains. That wasn't on 100 degree days though haha

If you've got a Cummins engine in there I would definitely go with a jake brake you would love it

We have an exhaust brake installed already😉

Allison transmission will hold up to a 360 horse power upgrade all day long. Built with massive shafts and clutches. Watch Gail Banks on You Tube to see what he is doing, amazing!

[@WanderingWagners]

We're familiar with Gale banks (we used to drag race). Allison told us not to do it as it would greatly shorten the life of the transmission as is. We've done enough diesel modification when we were drag racing to know the transmission is always the weakest link. It's just not worth it for the small amount of gains in hp/tq right now

[@johnmills3003]

Which exhaust brake and general cost?

[@WanderingWagners]

We went over the costs in this video! kzbin.info/www/bejne/Y57IoHeiqJWel9E The brake is internationals

[@jeffsharp5602]

Just the info I was waiting for from an experienced driver, Great videos very informative Thanks stay safe & create memories!

[@WanderingWagners]

Glad to help! Thanks for the comment, Jeff

[@bigjimsrealm4369]

So the rig didn't come with an exhaust brake? I'm surprised.

[@WanderingWagners]

No it didn't... It should imo but it didn't. We added it very easily at International

[@bigjimsrealm4369]

How much $ to add? Btw we are going to look at a 2023 Rebel 30R and the Wraith 34W.

[@WanderingWagners]

I believe the rebel comes with it but don't quote me on that. The Wraith does not and it was just under $500. And it took our dealer just an hour or so to complete.

@@WanderingWagners very impressive

[@fireincumbents]

Upping the horsepower / torque would be a non starter for me. If the transmission isn't rated for it, then you're asking for trouble. The exhaust brake DEFINITELY worth it.

[@WanderingWagners]

Exactly! The transmission is always the weak link. Just not worth the risk for a few more ponies

Fine job

There are always upgrades you can do but they'll cost a big ole pretty penny

[@wanttoplae]

Not sure of the proper terminology but does your exhaust brake have multiple stages/levels?

Ours is either on, or off.

I have a 2016 41ft Class A Holiday Rambler Endeavor with the ISL 9 380/1150, Allison 3000 with engine brake... I literally tell my wife the same “I’m not even touching the brakes” 🤣🤣 Class A’s with a Cummins 6.7 & Allison 2500 cap out at 340HP & 700 torque. Not sure if super c longer drive shaft length vs Class As impacts anything differently 🤷🏻‍♂️ I wouldn’t go over the recommended Allison 2500 specs unless you really want to buy a new one soon.

[@WanderingWagners]

Not touching the brakes is great! Haha we just don't want to upgrade power when it does a decent job as is, then chance the transmission having problems in the future because of it.

[@jeffsmith4525]

Love the exhaust brake on my F250

We had them on our (more recent) pickups but not standard on this unfortunately. We added it ourselves though!

Exhaust Brake for just what you were showing on your vedio. Never had to touch the brakes and came safely down the mountains.

[@WanderingWagners]

Absolutely. It makes mountain travel pretty simple and safe

"Commercial" trucks are always lower hp/tq.

I vote Exhaust brakes. It saves brakes and could save your life. Stopping is more important. I always have my exhaust brakes on in my Ram dually, and also in my semi(when allowed)

[@WanderingWagners]

Yeah we would rather put our money towards the brake. Ours is always on too haha

EB is the better bet here. You're traveling, not on a time line like the truckers, so you don't need to go 70 mph up & down in the mountains. Enjoy the scenery!

[@WanderingWagners]

We are on a timeline while traveling because we still work but understand your point haha👍🏻

[@hcrffi]

Upgrade on horsepower is great, but they should have Engine Brake or Retarder a standard before upgrading the engine. Stopping is the most important not the speed going up.

[@WanderingWagners]

We agree. The exhaust brake has been a great upgrade

[@ski3435]

You can see how Nexus cuts corners by installing a less powerful engine/transmission combo vs Entegra and Renegade. And no exhaust brake from the factory? Wow!

WICH ONE DO YOU OWN I DONT KNOW WHAT TO BUY ADAM AT COLERAIN SAYS TO AVOID SHOWHAULER

The super c performed quite well for having less hp/tq . That's why this coach is less expensive vs the renegade/entegra etc. They have the bigger transmission which can handle the higher hp/tq. We are with you on the exhaust brake! That should be standard
